MECHANISM FOR RECORDING THE MOVEMENTS OF STEERING-GEAR.

SPECIFICATION forming part of Letters Patent N0.'673,777, dated May 7, 1901.

Application filed NovemherZS, 1900. Serial No. 37,504. (No model.)

i To all whom it may concern.-

nologically every movement of the rudder of i a vessel from starboard to port,'and vice versa.

In order to record the movements of the rudder, I attach on the steering-wheel spindle a toothed wheel engaging with a train of wheels. Above the chain-spindle I fix a frame carrying two or more reels and a drum over which a tape passes. Near the said drum I vmount a pointer providedwith a'pencil or other suitable marking device. The said may be done by means of a worm or screw rotated by the aforesaid train of wheels, so

- that as thesteering-wheelis turned the penoil marks on'the tape the exact action of the rudder.; I provide suitable vmeans for causing the'pencil-point to travel in either direction for indicating starboard or port steering.

' According to this invention in order to have a chronological record of the above movements of therudder I provide a timepiece. By means of this timepiece rotary motion is imparted to a wheel or wheels, disk or disks,

1 bearing around its ortheir periphery or peripheries at regular intervals stamps for recording the time and date. The stamps are :kept inked, if necessary, bya ribbon or other suitable means. Means are provided for causing the time-stamps to continually advance and recede while the steering-wheel is being turned, thus automatically recording I the time of each movement of the rudder uponv the recording-tape before mentioned to one way of efiecting this backward-andforward motion of the time-stamps the said stamps are mounted in the case of the timepiece and the Whole case is capable of motion about a hinge. A rod is jointed to the case ward about its hinge.

and bears at its outer end an eccentric-strap. This strap embraces an eccentric which is turned by the turning of the steering-wheel,

so moving the said case backward and for- The length of the said eccentric-rod may be adjusted by means of adjusting-screws or otherwise.

I may mark the actual center line on the tape by means of a marking wheel or disk suitably mounted and supplied with ink;

The apparatus need not necessarily be fitted immediately above the rudder. It may be upon the bridge or at any part of the vessel where convenient.

In orderv that my said invention maybe better understood, I will now proceed to describe the same with reference to the drawings accompanying this specification, in Which- Figure 1 shows a side view of the apparatus, and Fig. 2 an end view of same.

y is a screw-spindle which carries the pinion w, and z a pencil-carrier traveling onscrewspindle yand kept from turning by the rod 11.

12 is a spring pressing upon the pepcil in the pencil-carrier z.

The action is as follows:. When the steer ing-wheel'is-turned, the bevel-wheel It or the bevel wheel it (according to which way the steering-wheel is turned) turns the crown- 3' zo to that in which the bevel-Wheelie turned);

will actuate the crown wheel on, so that this latter turns in the same direction as when actuated by the wheel in. This is necessary in order that the ribbon may be always drawn 'in thesame direction no matter which way' the steering-wheel is turned. The spindle causes the worm o to rotate, thus actuating the worm-wheel and tape-drum g. This drum q communicates motion by intermedi- The tape is first wound on the bobbinsand passes thence over the drum q to the bobbin r, on which it" 'is' wound. The rotation of the shaft d is communicated through thewheels u, v, and, 5'w and the pinion m to the screw-spindle y,f so that the pencil-carrier 2 is moved hack-v ward and forward along the said screw-spin-. dle according to the movement of the steero ate gearing 13to the bobbin "r.

thus indicating the times-at which the records of the various movements of the rudder were made.
